December 13, 2025 - Cu2O as an intermediate which is further reduced to the metal, and sulfur dioxide: ... Copper(I) oxide readily converts to copper(II) oxide when heated in the presence of oxygen, and to copper metal upon heating in a reducing environment.

Copper(I) Sulfide is a crystalline solid used as a semiconductor and in photo optic applications.

Copper(I) sulfide is used in luminous paints; antifouling paints; in solidlubricant mixtures; in solar cells; in electrodes; and as a catalyst.

August 12, 2025 - Prominent copper sulfide minerals include Cu2S (chalcocite) and CuS (covellite). In the mining industry, the minerals bornite or chalcopyrite, which consist of mixed copper-iron sulfides, are often referred to as "copper sulfides". In chemistry, a "binary copper sulfide" is any binary chemical compound of the elements copper and sulfur.

Copper(II) sulfide is used in antifouling paints, mixed catalysts and to develop aniline black dyes in textile printing. Further, it is used as a varnish pigment and an oxidizing agent.

This WebElements periodic table page contains copper sulphide for the element copper

It is a sulfide with an orthorhombic crystal system. The term chalcocite comes from the alteration of the obsolete name chalcosine, from the Greek khalkos, meaning copper. It is also known as redruthite, vitreous copper and copper-glance. ... Photovoltaic Cells: CuS is used in thin-film solar cells due to its semiconducting properties and ability to absorb sunlight effectively.

Copper sulfide (CuS) | CuS | CID 165914 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.

Copper is mainly absorbed through the gastrointestinal tract. All other intakes of copper (inhalation and dermal) are insignificant in comparison to the oral route. Sulfides: Sulfides of the heavy metals are generally insoluble and hence have little toxic action except through the liberation of hydrogen sulfide.
